I just acquired an Intel Series III MDS "blue box", to go along with
several Series IIs that I've had for a while.
Unfortunately, I don't have any software or documentation for either
the Series II or Series III, not even the ISIS operating system. If
anyone has spares or could make copies available, it would be most
appreciated.
For those not familiar with the Intel blue boxes:
The Series II MDS is Multibus-based, and has either an IPB-80 or IPC-85
CPU card, based on the 8080 and 8085, respectively. There's also an IOC
(Input/Output Card) that supports all of the integral I/O devices such
as the monitor, keyboard, serial ports, and single-density floppy disk.
An external double-density floppy disk system can be added; it uses two
Multibus cards, a channel card and an interface card, and apparently uses
M2FM code rather than IBM 3740-compatible MFM. The Series II normally runs
the ISIS operating system, although I hear there was also a version of CP/M.
A Series III MDS is mostly the same as a Series II with an IPC-85, but
it adds a two-board RPC-86, which is an 8086-based "Resident Processor
Card". A software package called "RUN" acts as the loader and ISIS
operating system interface for the 8086.
